Chapter 196 Experimental Hand Station
Zhu Xuemei jumped up excitedly.
"Don't worry, brother, I promise to look after the second brother."
Zhu Xuefeng touched the little sister's head. This girl wanted to ride on the second brother's head whenever she got the chance.
“If you have time, you should also find a few books to read. When writing a composition, you need to read more books and read them deeply. You must understand how to write and why you write like this, so that your composition will be fine. "
He turned to look at Zhu Xuesong again and said a few words.
"You two can arrange your own time later. I have to go to my godmother's house. I won't be back in the evening. Let's have breakfast together tomorrow."
It's probably about the phone, Zhu Xuesong deliberately packed the four semi-finished products and radio samples together and went out.
There was a slight breeze, it was really cold, and there were basically no people on the road. When I arrived at Director Wang's house, sure enough, I knew that Zhu Xuefeng was going home today, and Director Wang and Uncle Kong were waiting at home.
"Godmother, you are looking for me, uncle, you are here too."
"I'm not looking for it, I'm just running an errand for someone. This is the end of the military training. How about it? You're tired."
Director Wang came up to help unload the small bag and touched Zhu Xuefeng's face distressedly. .
“This little face is really dark. You say it’s just a military training. If you train in a ravine, you can’t train in school. I heard that many schools train on campus.”< br>
Uncle Kong usually would not disturb Director Wang during this time period and could only look at Zhu Xuefeng and smile.
"Godmother, didn't you say that it's not good to have a white face? Now it's a little darker, and you don't like it anymore."
"What nonsense are you talking about? When did Godmother not like it? Dark After reading so much, I know that you have endured a lot of hardships.”
Looked carefully up and down for a while and nodded.
"Not to mention, I have lost a little weight. This dark color makes me look more energetic. Not bad, I seem to be stronger. Go ahead. Your uncle is looking for you. He is almost running to your camp to find you. .”
Uncle Kong then took the opportunity to speak.
"Don't blame your uncle for being anxious. I read the letter you left. You said you couldn't just run a few more steps to come home. This made me wait for an extra month in vain. Come on, Let’s talk.”
Indeed, for a trip, this matter may have been made clear a long time ago, but now it is still necessary to make a trip. Zhu Xuefeng subconsciously does not want to enter the compound.
"Did you bring the radio? Let's take a look at your finished work first."
Zhu Xuefeng stood up and took out the radio from his bag. The appearance design is still good, but it is a bit rough. Of course the guys in the school factory can't compare to professional factories.
"Is this? So small?"
Zhu Xuefeng designed the most common medium wave and short wave dual-band radio. When Zhu Feng turned on the power switch of the radio, clear broadcasts came at the same time. Slowly adjust the station,
the effect is good, much better than the current big radio, with good sound quality and low noise.
Director Wang has already made tea, but did not make a sound. He quietly watched Zhu Xuefeng adjust the channel. He was a little surprised, but more happy. The last time his godson said he wanted to make a portable radio, how long had it been? , he really made it happen.
"It's really a radio. It's so small. I don't even know what to say about your hobby."
Uncle Kong didn't know how to express his emotions for a while. Seeing the letter and seeing the real thing are two completely different concepts. This kid's hands-on ability is really strong.
“Is it difficult to produce this thing? Can it be mass-produced?”
"Uncle Kong, this is not difficult to produce. Mass production depends on those transistor factories. It seems that their tubes are not open to civilian use yet. I don't know if other factories can do it."
(This radio uses nine transistors and one diode. At that time, there was a rule that civilian products could not exceed seven transistors, so everyone just pretended not to know)
He hesitated and added an explanation.
"The cost of this radio alone is more than 160. The main reason is that the tube is too expensive. I can't say the specifics." "You have the drawings. I'll hand them in for you tomorrow. Let them worry about the radio you mentioned. "
The radio is indeed a hot potato. Zhu Xuefeng is also worried about the future. With Uncle Kong taking over, he feels a lot more relaxed. Installing a radio is an obsession. Now it seems that there are still many difficulties ahead, so it might as well give up.
This mobile phone is what Uncle Kong is most concerned about. I heard that Zhu Feng has successfully experimented, so I am waiting for the battery. I have been looking for the relevant departments during this period. This does not force the relevant departments to study hard and finally get it. I bought a few batteries and can’t wait to try them now.
“I brought it with me too. There are four sets in total. They have all been tested and there is no problem. I just don’t have batteries and can’t try them.”
Uncle Kong smiled mysteriously, got up and went to the study to get the He brought out a big box, placed it on the table, and patted the box.
“I’ve also found a few sets of the batteries you want. How about we try them now.”
Zhu Xuefeng looked at Uncle Kong in surprise. How could this battery be so easy to make? Could it be that Lao Mei's battery was obtained through special channels?
I opened the box with hesitation, I was so happy for nothing, I really thought too much, how can the old American battery be so easy to deal with.
There were six batteries lying in the box, which were twice as big as Zhu Feng had requested. Zhu Xuefeng picked them up and looked at the parameters, and finally understood.
The parameters are all in compliance with the requirements. I must be in a hurry. Let's make a cross with qualified parameters. There is no other way. Let's try it.
Seeing Zhu Xuefeng's dumbfounded expression, Uncle Kong also realized something was wrong and asked quickly.
"Can't you use this?"
"It does work, but Uncle Kong, the thing I designed is called a handheld device. You can grab it with just one slap. Look, you can take this battery. It’s hard enough to hold it, it’s too big.”
Uncle Kong was a little speechless. Indeed, this thing is too big to be held with one hand. It’s almost enough to hold it with two hands.
“Don’t worry, let’s try the effect first. The battery needs to be researched quickly. After all, the new battery is still a new field for them, so they have to be given time.”
< br>Zhu Xuefeng suggested imitating the old American products and directly researching nickel-chromium batteries. As for nickel-metal hydride batteries and lithium batteries, it is too early and unrealistic.
But the technology accumulation of the Beijing Battery Factory is far from enough. It only solved the technology of dry batteries a few years ago. Now it has jumped so much at once, which is really embarrassing.
As for the chemical factory that Section Chief Lu is looking for, Zhu Xuefeng doesn’t have much hope. Their battery is lead-acid battery technology. It’s still early to start researching it now. I’m thinking about finding time to go shopping on Taobao. No chance.
It stands to reason that domestic research on the batteries that are used now will not begin until ten years later. It is said that according to the requirements of Uncle Kong and his department, many experts have been mobilized to tackle the problem and have already started. There may be a chance of this .
Zhu Xuefeng connected the line, set up a few scattered stalls, adjusted the channel, and gave it a try. It should be fine.
"Uncle Kong, I have adjusted everything. No matter how you test it, you can't go out for an interview with this bunch of stuff."
Uncle Kong looked at the puddle on the table and said They were all connected to wires and couldn't be lifted or hugged. It was really a bit difficult. He rarely lit a cigarette, and Zhu Xuefeng had no choice but to smoke with him.
"On this matter, you two are having sex at home. As for why you are so gloomy, Lao Kong, just call a car and let it go."
< br>"Yes, why didn't I think of that."
Uncle Kong quickly got up and went to the study to ask for a phone. He came out after a while and asked Zhu Xuefeng.
"Xiaofeng, how far can this thing of yours travel?"
Zhu Xuefeng thought for a while. There were not many buildings in the city now, and there was basically no radio interference.
“This sample should work within two kilometers in the city, and it should also work within ten kilometers on the sea!”
A jeep took away a set of mobile phones and batteries. Uncle Kong also followed the car and left, leaving only Director Wang and Zhu Xuefeng at home guarding the other station, waiting for Uncle Kong's call.
